IMPROVEMENT m WINDMILLS.

Specification forming partof Letters Patent N 0. 177,625, dated May 23,1876; application filed April 25, 1876. I

To all whom it may concern:

Be it known that I, EBHRAIM DICE, of Seioto, in the county of McDonoughand State of Illinois, have invented certain new and useful Improvementsin Windmills; and I do hereby declare that the following is a full,clear, and exact description thereof, that will enable others skilled inthe art to which it appertains to make and use the same, ref erencebeing had to the accompanying drawings, and to the letters andfigures ofreference marked thereon, which form a part of this specification.

The same letters and figures of reference are used to indicate thecorresponding parts.

After describing the invention, its nature and extent will be shown inthe claims.

Figure l is a vertical sectional view of my windmill, taken through thevane and wind- Wheel. Fig. 2 is a rear View of the windwheel, taken nextto the tower. Fig. 3'is a sideview of a part of the turn-table and ofthe sliding hub. Figs. 4, 5, 6, and 7 are detail views.

the turn-table, and connected with the reciprocating rod (1. E" is a hubsleeved 011 the shaft, the outer end of which is connected with thelever 12, pivoted at c, and provided with the weight 6. The disk F isfixed to the sliding hub near its outer end. To the lugs f f on the diskF are pivoted the levers g h la, and connect the disk F with thesections G G of the wind-wheel. The shaft D extends beyond thewind-wheel, and to it are eonnectedthe truss-rods H H, which also areattached to the arms I I, and these form the frame-work of the wheel. KK are curved arms, firmlyfastened to the hub of the windwheel, and serveas a fulcrum to enable the levers g, h, and k to act, through thesliding hub, on the weight c, and thus move the sectional sails of thewind-wheel out of the force of the wind when it is too strong. On theend of V the shaft D is screwed a small disk, I, to which the truss-rodsH H are attached.

These trussrods are indispensable in a wind-wheel composed of sectionalsails arranged as my invention is, the requisite strength and wheel.

1 X is a small iron bar, bent at right angles at either end, andfastened to the bottom of each section of the wind-wheel, and meets inorder to give firmness to the the curved arm K, when the sections are soturned as to receive the force of the wind. The use of X is to preventthe sections from being turned out of the force of the wind by thecurved. projecting arms K K, mortised into the hub, in combination withthe shaft D and-the truss-rods H H, substantially as described, and forthe purposes set forth. 7

2. The righ t-angled lever b, pivoted at c, and provided with the weight6 at one end, and slotted at the other end to embrace the slidin g hub,in combination with, the sliding hub E and the connecting-levers g, h,and k, the lever It being pivoted at the arm K, which acts as a fulcrumfor the whole series of levers, the extended shaft D, and the truss-rodsH H, substantially as described, and for the purposes specified.

In testimony that I claim have hereunto set my hand March, 1876.

the foregoing I E'BHRAIM DICE.
